RAID 5E, RAID 5EE, and RAID 6E (with the added E standing for Enhanced) generally refer to variants of RAID 5 or 6 with an integrated hot-spare drive, where the spare drive is an active part of the block rotation scheme. This spreads I/O across all drives, including the spare, thus reducing the load on each drive, increasing performance.
Diagram of a RAID 0 setup. RAID 0 (also known as a stripe set or striped volume) splits ("stripes") data evenly across two or more disks, without parity information, redundancy, or fault tolerance. Since RAID 0 provides no fault tolerance or redundancy, the failure of one drive will cause the entire array to fail, due to data being striped ...
RAID 01, also called RAID 0+1, is a RAID level using a mirror of stripes, achieving both replication and sharing of data between disks. [3] The usable capacity of a RAID 01 array is the same as in a RAID 1 array made of the same drives, in which one half of the drives is used to mirror the other half.
The amount of data in one stride multiplied by the number of data disks in the array (i.e., stripe depth times stripe width, which in the geometrical analogy would yield an area) is sometimes called the stripe size or stripe width. [5] Wide striping occurs when chunks of data are spread across multiple arrays, possibly all the drives in the system.
RAID (/ r eɪ d /; redundant array of inexpensive disks or redundant array of independent disks) [1] [2] is a data storage virtualization technology that combines multiple physical data storage components into one or more logical units for the purposes of data redundancy, performance improvement, or both.
The Israeli Prime Minister's Office stated that Israel has adopted the report, except for its conclusions regarding the use of force in the flotilla raid. [296] Turkey criticized the report for accepting Israel's naval blockade as legal, and Turkey's president Abdullah Gul said his country considered the report "null and void". [ 297 ]
A blood stripe is a scarlet stripe worn down the outside leg seams of trousers on the dress uniform of the United States Marine Corps. This red stripe is 2 inches (5.1 cm) for general officers , 1 + 1 ⁄ 2 inches (3.8 cm) for other officers, and 1 + 1 ⁄ 8 inches (2.9 cm) for enlisted staff noncommissioned officers and non-commissioned officers .
The Doolittle Raid, also known as Doolittle's Raid, as well as the Tokyo Raid, was an air raid on 18 April 1942 by the United States on the Japanese capital Tokyo and other places on Honshu during World War II. It was the first American air operation to strike the Japanese archipelago. Although the raid caused comparatively minor damage, it ...
